Sony FE 90mm f/2.8 Macro G OSS Full-Frame E-Mount Macro Lens

The full-frame 90mm medium telephoto macro E-mount lens features built in image stabilization for sharp, clear images at up to 1:1 magnification, even when shooting handheld. Advanced optics and coatings with a 9-blade circular aperture deliver exceptionally smooth bokeh that G Lenses are renowned for. Sharp in-focus rendering is achieved with a floating focus mechanism that suppresses aberration equally at all focusing distances, whether the subject is far away or extremely close. Other advanced technologies, such as the Nano Anti-Reflective Coating and Super ED (extra-low dispersion) glass, elevate overall performance to an extremely high standard.

Nano Anti-Reflective Coating

Effectively suppress reflections that can cause flare and ghosting with Sony’s original Nano Anti-Reflective Coating technology. This precisely defined regular nano-structure allows accurate light transmission, contributing to high-quality images, even more so than lenses with coatings that use an irregular nano-structure. The reflection suppression characteristic of the Nano Anti-Reflective Coating is superior to conventional anti-reflective coatings, providing a notable improvement in clarity, contrast, and overall image quality.

Circular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

Aspherical Lens Elements

Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped aspherical elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.
